To all whom it may conce-rn:

a itknown that I, Cuirr J. BAL-rimani, aA citizen o f the- UnitedStates, and resident of Sh Louis,- Missourl, have invented certain new'andaiseful Improvements in Thermo- Static Begulators, of which thefollowing is a -.spec1 ficat 1on containing a full, clear, and egactdescription, reference being had to the accom' anying 4drawings, forminga part am@ i inventionl relates toa thermostatic ator, and consists ofmeans which op fera/.te automatically to maintain Water or ,othervluidat a uniform temperature by controlling the Supply of heat to said Wateror aan.

' 'traction of the airin the chamber due to the changes in temperatureof the fluid passing through yand said diaphragm operating a suitableinvention further consistsin a double livalled air chamber, 1n one endof which is arranged a diaphragm which is elevated and lowered as aresult' of the expansion and conthe doublewalls of Isaid chamber,

mechanical device, such as adamper or valve, the heating mechanism.

, To the above purposes, my invention con sist-sin .certain novel'.features of construction andai-rangement of parts,l which will .behereinafter more/fully set "forth, pointed out in the claims, andillustrated in the accompanying drawings, in which Figure 1 is a sideelevation of a hot Water tank with my .improved thermostatic regulatorattached thereto, and being shown in vertical section; Fig. 2 is a planView of the regulatpr; Figiis a plan view of the regulator,.with theadjustable ring which carries an 'operating lever removed therefrom. l

Referring by numerals to the accompany# ing 'drawings :-1 designates alhot water tank, 2 the steam pipe leading thereinto,

which provides means for heating the water in said tank, and in whichsteam pipe is located abalaneed valve 3.

4 designates a double Walled conical chambedr, andA leading into thelower end thereof 'the pipe 1G performs the function from the upper endof the tank 1 is a pipe 5, in which i located a valve 6. Leading fromtheupper end of the chamber l is a pipe 7, in which is located a valveS, and said pipe T connects with a service pipe 9. Connecting 5 with`the service pipe 9 is a pipe 10, in which is .located a valve 11, whichpipe of a by-pass when v 4Specificatie.n of Letters IlaartentTApplication iled October 1,

"the thermostatic regulator is out of use, and.

the valves and Sare closed.

`Rigidly fixed in any suitable manner on top of the chamber t a cap 11,and held betiveen the edge thereof and the top of the. conical chamber.L1 is a flexible diaphragm 12, of rubber, or analogous material, andlocated o n top ofsaid diaphragm is a sleeve 13, which operates throughan opening 11iy formed in the center of the cap 11. The arrangement ofthe diaphragm 12 on top of the chamber 4 .creates an air-tightcompartment Within said chamber below said dla-l phragm. -l

IArranged for rotation on top of the cap 11. is a ring 15, and fixed inone side thereof isa bracket 16, in .which fulcrumed a horizontallydisposed lever "17. This lever ex- `tends across the top of the cap 11,and its outer end is provided 'with an adjustable weight 1S. A pin 19 isadjustably seated in the ring 15 -opposite the bracket 16 and. serves asa rest for the outer end of the leverl 17 \vhen'the same occupies ahorizontal position, and located in the sleeve 13 is a pin 20, .the'upper end of which is bifurcated and engages the lever 17 between thefulcrum point and the weighted end thereof. The end of the lever 16opposite. the Weighted end 'is connected in any suitable manner to thestein oi the balanced valve Z.

When my improved regulator is in use, the steam discharging from thepipe 2 heats `Water in the tank 1, and the water thus heated passesthrough the pipe 5, between the double walls of the chamber 4, through9. When the temperature of the Water rises above the normal degree, theair o n thev interior of the air tight chamber L1 will be the pipe 7,and out through the service pipe expanded by said heat, and, as aresult, the' diaphragm 12 will be elevated. This action elevates thesleeve 13 and pin 20, in turn elevating the Weighted .end ofthe lever17, swinging the same .upon its fulcrurn, and thus operating thebalanced valve 3` to cut off, or partiall 1' cut off, t-he passage ofsteam through thepipe 2, which heats the Water. As the steam to the tank1 is thus out off or reduced, the temperature in said tank willnaturally fall, until the proper degree of temperature is reached, andthus a practically stationary temperature is maintained as long as the'regulatqr is in use. Should inoperative for any for' should it vbedesired to di with the-'use thereof,'the `valves .6 and'8 areclosed,`and the-hot water Twill discharge frOmQthepipe thrugh the:by-pass 'pipe 10 direct to thev service pipe. 9.
